Abstract:Dedicated short-range communication systems have been proposed for operation at
locations across the United States in the 5850- to 5925-MHz band. Various search
and tracking high-power radars operate at or near this frequency band and are a
source of potential interference. The successful operation of such digital
communication systems is dependent upon compatible operation and coexistence with
these radars. The Institute for Telecommunication Sciences has performed a series
of interference tests to determine the electromagnetic compatibility of DSRC systems
used for automatic toll collection and high-power 5-GHz radars. The methods used
to perform the tests and results are presented in this report.
